NXP Semiconductors MCF52211CVM66

Overview

MCF52211CVM66 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller in 64-pin LQFP (10 mm × 10 mm), operating up to 66 MHz with 128 KB flash and 16 KB SRAM. It integrates USB OTG, three UARTs, dual I²C, QSPI, 8-channel 12-bit ADC, four 32-bit DMA timers, and real-time clock - deployed in industrial control panels requiring deterministic timing and field-upgradable firmware.

For engineers reviewing the MCF52211CVM66 datasheet, MCF52211CVM66 pinout, MCF52211CVM66 application, or MCF52211CVM66 equivalent, key selection criteria include its 66 MHz V2 ColdFire core performance (76 MIPS Dhrystone), integrated USB OTG host/device capability, 12-bit ADC simultaneous sampling for motor feedback, and support for BDM/JTAG debug on 64-pin packages despite reduced trace functionality versus 100-pin variants.

Technical Context

The MCF52211CVM66 implements the ColdFire ISA_A+ instruction set with hardware MAC unit and 32-bit accumulator, enabling efficient 16×16 and 32×32 multiply-accumulate operations for embedded signal processing. Its PLL supports system clock derivation from crystal, on-chip 8 MHz relaxation oscillator, or external source, with programmable dividers and low-power mode retention.

On-chip peripherals are tightly coupled via the local bus: dual-ported SRAM enables concurrent CPU/DMA access without contention; flash memory uses interleaved 2-1-1-1 read timing; and the interrupt controller provides 57 sources with individually programmable priority and vectoring - critical for real-time response in motion control and HMI applications.

FAQ

What is the maximum operating frequency of the MCF52211CVM66?

The MCF52211CVM66 operates at a maximum core frequency of 66 MHz, delivering 76 MIPS (Dhrystone 2.1) when executing from internal flash memory. This frequency is achieved using the on-chip PLL locked to an external crystal or the internal 8 MHz relaxation oscillator, with programmable dividers ensuring stable operation across voltage and temperature ranges.

Does the MCF52211CVM66 support USB device and host functionality simultaneously?

Yes, the MCF52211CVM66 integrates a USB On-The-Go (OTG) controller that supports both full-speed/low-speed device and host modes. It includes 16 bidirectional endpoints and DMA/FIFO data paths, allowing the MCF52211CVM66 to enumerate as a CDC ACM serial device when connected to a PC or act as a host to read from USB mass storage devices - all without external PHY components.

How many analog input channels does the MCF52211CVM66 ADC support, and what is its resolution?

The MCF52211CVM66 features an 8-channel, 12-bit successive approximation register (SAR) ADC with a minimum conversion time of 1.125 µs. It supports simultaneous sampling on two channels using independent sample-and-hold circuits - a key capability for motor control applications requiring synchronized current measurements - and allows unused analog inputs to be repurposed as general-purpose I/O pins.

What debug interfaces are available on the MCF52211CVM66 64-pin LQFP package?

The MCF52211CVM66 in 64-pin LQFP supports Background Debug Mode (BDM) and IEEE 1149.1 JTAG via dedicated pins (TMS, TDI, TDO, TCK, TRST). While full real-time trace is limited to 100-pin packages, the 64-pin variant retains the ALLPST signal and dedicated debug serial channel (DSI/DSO/DSCLK), enabling breakpoint-based debugging, memory inspection, and firmware download without requiring external emulators.

Is the MCF52211CVM66 pin-compatible with other members of the MCF5221x family?

The MCF52211CVM66 shares the same 64-pin LQFP mechanical footprint and signal mapping with the MCF52210CVM66 and MCF52213CVM66, making them pin-compatible within that package variant. However, functional differences exist - such as flash/SRAM sizes, presence of secondary watchdog, and UART count - so firmware and PCB design must validate peripheral availability and memory layout before substitution.
